The current user interface (UI) of NEIS school affairs business system is not efficient in conducting the business because of complicated data input forms as well as unharmonious connection between similar items and functional menu. In the paper, the term UI means a comprehensive concept including input/output, input/output related functionality, and menu configuration for users to perform their tasks. The first survey, carried out with one hundred teachers at three elementary schools of Kyeonggi-do, shows that the UI problems of the system are manual inputs, inconvenient menu configuration, disconnection between academic calendar and educational process, complexities of managing attendance report and curriculum evaluation, etc. We have improved the UI design by providing more efficient input method and more systematic menu configuration compared to the current system, and then evaluated the design through the second survey. Evaluation results show that users prefer the proposed UI design especially from the viewpoint of user-friendly input interface and user-oriented view composition.

The purpose of this study was to evaluate performance and subjective satisfaction of mobile phone's interface elements considering the elderly users. First, mobile phone's interface elements were outlined recent foreign and domestic studies. Then, final three mobile phone's interface elements were determined by expert rating, AHP analysis, and questionnaire analysis. Objective and subjective measures were then used to determine the effects of several specific design parameters and aging differences on performance of mobile phones. In this experiment, 38 subjects and 4 independent variables were used to measure task completion time and user's subjective satisfaction. The statistical analyses indicated significant aging differences between older people and younger people in terms of keypad type and bell sound level in performance. Significant aging differences were also found for user subjective satisfaction. It is suggested that some major results from this study be used to develop mobile phone design guidelines that are more usable and accessible for most users, particularly for older users.

Interactive TV의 주요 특징으로 고품질, 다채널, 다기능, 양방향성, 지능형 등을 들 수 있는데 그 중에서도 다채널화로 시청자들이 원하는 프로그램을 얼마나 쉽게 빨리 찾을 수 있을 것인가가 문제시되고 있다. 이러한 문제점을 해결하기 위해서는 EPG(Electronic Programing Guide) User Interface Design을 함에 있어 레이아웃, 컬러, 텍스트, 아이콘 등의 시각적 요소들과 네비게이션이 잘 구성되어야하고 디지털방송시스템의 기능적인 구조적 특징들이 잘 어울려질 때 진정한 EPG의 사용자 인터페이스 디자인이 탄생한다. 본 연구에서는 현재 방송사들이 사용하고 있는 EPG의 인터페이스 디자인을 분석하고 Interactive TV의 인터페이스 디자인에 관하여 문헌을 통한 연구를 한다. 이를 통해 새로운 EPG 인터페이스 디자인을 들어감에 있어 가이드라인을 제시하고자 한다. 사용자가 좀 더 편리하고 쉽게 사용할 수 있는 디자인을 개발하여 시청자들이 편리하게 사용하여 Interactive TV와의 대화가 원활하게 수행될 수 있도록 하는 것이 본 논문의 궁극적인 목적이다. 향후 본 연구에서 제시한 EPG 사용자 인터페이스 디자인 가이드라인이 EPG를 User Interface Design함에 있어 하나의 좋은 지침서가 될 것이다.

It has been designed GUI(graphic user interface) to consult the convenience of a input data and the flexibility that can be retrieved dismantling information relation to decommissioning DB of KRR1&2. The GUI can proceed an input materials and a search and output of a saved data in server based on a facility code and also have a function of explorer which can find the lower dismantling objects in each facilities. It has added the structure of the multimedia that could be showed a series of dismantling activities with a Mpeg and pictures into the GUI. In the future work, Decommissioning DB and User Interface are intend to contribute a functions that could be evaluate and analyze for a dismantling activities with a engineering theory.

디지털 방송의 시작과 함께, TV화면에서 채널이나 프로그램을 직접 검색할 수 있는 EPG(Electronic Program Guide)라는 새로운 방송 서비스가 제공되고 있다. 그러나 아직까지는 시청자 입장을 고려한 EPG의 User Interface에 대한 연구는 미흡한 실정이다. TV는 특정 계층이 아닌 모든 사람이 시청하는 매체이의로 시청자에게 프로그램을 쉽게 찾게 하기 위해서는 단순하고 직관적인 User Interface가 필요하다. 이러한 User Interface를 설계하기 위해서는 많은 채널에서 방송되고 있는 프로그램을 체계적으로 구분학 수 있는 정보구조와 정보구조들을 유연하게 연결시킬 수 있는 Navigation의 설계가 필요하다. 일반적으로 프로그램을 구분하는 방법으로 장르, 시간, 등급, 프로그램의 내용 등과 같은 속성을 이용한다. 하지만 이러한 속성들은 체계적으로 구조화되어 있지 않다. 본 논문에서 제안하는 EPG는 프로그램이 가지는 속성들을 체계적으로 정리해 구조화하고, 이렇게 구조화된 속성들을 시청자들이 쉽게 선택해 원하는 프로그램을 찾을 수 있는 유연한 Navigation을 설계함으로써 기존의 EPG보다 쉽고 빠르게 프로그램을 검색 학 수 있는 User Interface를 제안하고자 한다.

The recent growth of the robot technology has made robots be popular and provides people with many opportunities to apply various robots. But most robots are controlled by its unique program, users feel hard and unfamiliar with robot. Therefore we need to find ways to make user feel comfortable and familiar with the usage of robot. First we will analyze how the user interacts with the robot. Next we will discuss a standard human-robot interface provide more usability with that analysis. In this paper, 10 degree of the Level Of Autonomy(LOA) are proposed. It is evaluated that what interface components and designs are proper to each LOA. Finally we suggest a way to design the standard human-robot interface for remote controlleds robot through handheld devices like the Personal Digital Assistant(PDA) and smart phone.

Based on the theory of space perception, this paper concludes that the mixed reality application under the theory of space perception has a three-level definition of visual hierarchy and then analyzes the component elements of interface design and the classification mode of interface windows. Next, carry out case practice research through this theoretical definition, and finally conduct the survey and analysis of questionnaire data, verifying that the mixed reality interface design based on spatial perception theory meets the user experience elements of Usability, Availability, and Attraction. The conclusion is that the constituent elements of interface design and the window classification mode can provide specific and practical design specifications for mixed reality interface design, reduce the interaction cost of completing tasks, reduce users' cognitive load, and make it easier for users to receive interface information

Recently, it is more important to do part of software designers for developing user-centered software. They produce visual document for helping communication between developers and visual diagram for analyzing user need factors based on user scenario. Case study of architecture real dispatch service can show developing samples. It is important to produce visual document for one combined opinion between developers in process of defining of development boundary, main concept development, selecting of development system. And visual document process with visual language by software designer is step for recognizing of user need factors before developing interface design in process of collecting design factors of user and environment and analyzing design factor by user scenario. Also, in process of interface and prototype development, it need visual document for peaceful and concord process between developers. Those visual documents with visual language could help to define developers role and duty, user-centered concept development and various interface development proposal during software developing.
